You will need to feed them locus and crickets and they should last up to 10 days then you can leave it for 4 days the refill. Thats what I do. But geckos can live up to 4 weeks without food.
How Often Do Geckos Have To Eat?
It does depend on how old they are younger geckos can be fed small amount daily so they don't have to digest a large meal like maybe an adult gecko would, it does vary on the appetite of your gecko to as you get to know them . Mine eat every other day they have maybe 2 meal worms each and maybe 3 or 4 crickets they know when they have had enough and maybe one day in the week I will feed them wax worms as a treat maybe just 2 or 3 each and no crickets its all personal preference and what your geckos enjoy the most(usually wax worms! They are high in fat so not to many think of them as a bar of chocolate we love it but shouldnt eat it every day lol! Hope this helps.
When I feed my gecko, I give it 3 crickets then I'll feed it after 3 days.
How often should you feed a fat-tailed-gecko baby food????? I looked what to feed geckos and it said baby food is best, too.
